5 drraav ys" United States Patent 3,122,061 RECOIL SPRUJG GUIDE AND MUZZLE WEIGHT Maxweil G. Atchisson, 1845 N. Garfield, Hoilywood, Calif. Filed May 17, 1962, Ser. No. 195,449 4 Claims. (Cl. 89-198) This invention relates to an improved recoil spring guide and weight for a pistol.

It is an object of this invention to provide an improved recoil spring guide which may readily be inserted into the gun without major modification thereof which guide will prevent kinking of the recoil spring and insure a smooth recoil action.

A further object of this invention is to provide an improved recoil spring guide which permits the addition of weight thereto, to steady the gun during firing and reduce recoil upon firing.

Still a further object of this invention is to provide means whereby such weight may be added without major modification at the optimum position to produce the desired steadying effect and recoil reducing effect.

Other objects and advantages will be readily apparent from the following description:

In the drawings:

FIGURE 1 is a side elevation of a pistol having means embodying this invention.

FIGURE 2 is a fragmentary section of the pistol showing the recoil spring guide with Weight attached.

FIGURE 3 is a section taken along line 33 of FIGURE 2.

FIGURE 4 is a view similar to FIGURE 2 showing the recoil spring guide without the Weight.

Generally illustrated in the drawings is a Colt 45 automatic pistol to which this invention is particularly adapted. Such pistol has a recoil spring bore therein parallel to the barrel 12 which bore houses recoil spring 14, a recoil spring guide 16, and a recoil spring plug 26. The guide is cylindrical having a flange 18 formed I thereon. A threaded insert 20 is fixed on the inner end of the guide 16. A recoil spring guide extension shaft 22 has a cylindrical exterior approximate in diameter to that of the guide 16 and a threaded rear extremity 24 of reduced diameter which projects through guide 16 and screws into threaded insert 20. A recoil spring plug 26 is hollow permitting passage of shaft 22 therethrough and of sufiicient inner diameter to receive the extremity of the recoil spring 14.

The plug has a shoulder 30 formed thereon which abuts the barrel bushing 32 retaining the device in bore 10.

As seen in FIGURE 4, the thus formed recoil spring guide means will prevent any possible kinking of the recoil spring and add some Weight to the muzzle end of the weapon.

In FIGURE 2 an additional weight 34 has been added to the extension shaft 22. This weight is cylindrical in shape and has a tapered shaft joining portion 36 which prevents blow forward from the muzzle blast upon firing.

This positioning of the weight forward from the pistol grip assists in steadying the gun during aiming and reducing the recoil and thereby reducing the tendency of the gun to jump up upon firing which is of great aid in rapid firing.

3,122,061 Patented Feb. 25, 1964 ice At the outermost extremity of shaft 22 or weight 34 if such is utilized, a non-circular depression 38 is formed to receive a non-circular wrench to facilitate assembly or disassembly.

While what hereinbefore has been described is the prefered embodiment of this invention, it is readily apparent that modifications and alterations can be made without departing from the scope of the invention.

I claim:

1. A recoil spring guide for a pistol having a bore housing a recoil spring comprising: a recoil spring guide Within said bore, said guide being cylindrical and having a bore therethrough and threads formed in said bore, a cylindrical recoil spring guide extension shaft of the approximate diameter as said guide, said shaft having a reduced threaded extremity projecting into the bore of said guide, and a recoil spring plug loosely fitting upon said shaft and a recoil spring fitting upon said shaft fitting within said plug and abutting said guide.

2. A recoil spring guide for a pistol having a bore housing a recoil spring comprising: a recoil spring guide within said bore, said guide being cylindrical and having a bore therethrough and threads formed in said bore, a cylindrical recoil spring guide extension shaft of the approximate diameter as said guide, said shaft having a reduced threaded extremity projected into the bore of said guide, a recoil spring plug loosely fitting upon said shaft, a recoil spring fitting upon said shaft fitting within said plug and abutting said guide, and a Weight attached to said shaft in advance of said bore.

3. A recoil spring guide for a pistol having a bore housing a recoil spring comprising: a recoil spring guide within said bore, said guide being cylindrical and having a bore therethrough and threads formed in said bore, a cylindrical recoil spring guide extension shaft of the approximate diameter as said guide, said shaft having a reduced threaded extremity projected into the bore of said guide, a recoil spring plug loosely fitting upon said shaft, a recoil spring fitting upon said shaft fitting within said plug and abutting said guide, and a weight attached to said shaft in advance of said bore, said weight having a tapered portion connecting same to said shaft.

4. In a pistol having a bore, a cylindrical recoil spring guide having a bore therethrough mounted in said bore and extending along a portion of the length thereof, a recoil spring fitting upon said guide, and a recoil spring plug for receiving one end of said spring, the improvement comprising: a threaded insert mounted in said bore of said spring guide, a cylindrical recoil spring extension shaft of the same approximate diameter as said guide, one end of said shaft having a reduced threaded extremity projecting into said bore and said guide and threadedly engaging said insert, the other end of said shaft passing through an opening formed in said plug, said recoil spring fitting upon said shaft, fitting within said plug, and having one end abutting a portion of said plug and the other end abutting a portion of said guide.
